The Post team on Tuesday hosted the second installment of the Executive Smarts series with a lively discussion on the many ways in which the health care sector is changing. The event — held at the Listening Room Cafe on Second Avenue and sponsored by CapStar Bank, Frazier & Deeter and Peak10 — featured Larry Nall of BlueCross BlueShield of Tennessee, John Deane of Southwind/Advisory Board and Larry Van Horn of Vanderbilt. Veteran health care entrepreneur Jim Lackey of Complete Holdings Group moderated the exchange. Look for excerpts of the discussion in June's Healthier magazine.
